[C] t(s) 0 1.000000 100 0.778801 200 0.606531 300 0.472367 400 0.367879 500 0.286505 600 0.223130 800 0.135335 1000 0.082085 1200 0.049787 The process is governed by the rate law given by the equation: = In (SO3)-kt+In (SO3)-0 Where k is the rate constant and t is the time, and In is natural logarithm. By calculating the corresponding values of In[SO3] and plotting the graph of In [SO3] against time, t, determine the rate…

Qu 4 Silver has FCC crystal structure at room temperature, and a lattice constant, a, of 0.407 nm. Draw a reduced sphere silver unit cell in the grids provided below, clearly label the lattice dimensions. Within the unit cell you drew, shade the (1 0 0) plane. How many atoms are contained within the (1 0 0) plane? Calculate the area of (1 0 0) plane in [nm?]. Express your answer in [nm?] to three significant figures. Calculate the planar density of the (1 0 0) plane in [atoms/nm?]. Express the answer in atoms/nm to three significant figures.  show all work step by step
